I have a client whom I want to give as much Dashboard control over the admin area as possible. I know how to create a custom dashboard widget that contains just text/html but I have no idea how to create one that contains just a single text input field.
Adding the form html would be straightforward I can see that but I don't know:
- Where to submit the form data too
- How to redirect back to the Dashboard after the form is submitted
- How to retrieve the value in my non-admin theme templates
